|
| +# The tests in this file check that the following two bugs (both now fixed)
|
| +# do not reappear.
|
| +#
|
| +# jrnlmode2-1.*: Demonstrate bug #3745:
|
| +#
|
| +# In persistent journal mode, if:
|
| +#
|
| +# * There is a persistent journal in the file-system, AND
|
| +# * there exists a connection with a shared lock on the db file,
|
| +#
|
| +# then a second connection cannot open a read-transaction on the database.
|
| +# The reason is because while determining that the persistent-journal is
|
| +# not a hot-journal, SQLite currently grabs an exclusive lock on the
|
| +# database file. If this fails because another connection has a shared
|
| +# lock, then SQLITE_BUSY is returned to the user.
|
| +#
|
| +# jrnlmode2-2.*: Demonstrate bug #3751:
|
| +#
|
| +# If a connection is opened in SQLITE_OPEN_READONLY mode, the underlying
|
| +# unix file descriptor on the database file is opened in O_RDONLY mode.
|
| +#
|
| +# When SQLite queries the database file for the schema in order to compile
|
| +# the SELECT statement, it sees the empty journal in the file system, it
|
| +# attempts to obtain an exclusive lock on the database file (this is a
|
| +# bug). The attempt to obtain an exclusive (write) lock on a read-only file
|
| +# fails at the OS level. Under unix, fcntl() reports an EBADF - "Bad file
|
| +# descriptor" - error.
